Sokar Feast

Sokar Feast
Sometime later in the Old Kingdom, after the ascendence of Osiris as the principal mortuary god from Heliopolis, this god was grafted on too, and the composite Ptah-Sokar-Osiris was formed.

The Sokar Feast was celebrated every year at the setting (disappearance from the night sky) of the constellation Orion, which was a symbolic death of Ptah-Sokar-Osiris. The rites center around the preparation of his body, actually a corn Osiris which would later sprout after watering, and its placement into a tomb, but the culmination of the ceremonies involved the resurrection of the god in the form of the full moon rising on the lotus of Nefertum.
